Abstract:
The work of the current thesis deals with an exhaustive analysis of the cohort of PCIs on OTCs of our center over several years since the establishment of a program dedicated to this field. In the first study, the predictive capacity of the J-CTO score was studied in a cohort of more than 500 patients and it was investigated whether the model can adequately predict the success of the procedure, taking into account the progressive experience of the center in this field. It should be noted that the J-CTO score was developed from a cohort of ICPs on CTOs carried out by expert operators. In the second study we have analyzed the variables that best predict the success rates of the procedure in our cohort and we have included the operator experience variable as a potential influencing factor, an aspect not quantified in other studies. The third study analyzes and compares those OTCs with failed PCI and who underwent a second attempt with the PCIs of the first or only one attempt. A comparison of the degree of complexity and the success rates between both groups is made. Those possible contributing factors to the success of the procedure in the new attempt are specifically sought and analyzed, such as angiographic changes in the second attempt compared to the previous one and the use of new strategies and techniques in new attempts.
